A second approach is to define a set of desirable properties, or axioms, that a method should have [1]}, [2]}. Examples of such axioms include local accuracy, missingness and consistency [1]}. Such approaches are more objective in nature, but recent work has shown that methods that conform to these axioms are still not necessarily accurate [4]}. Some of these axioms can also be implemented in different ways, leading to a number of methods that all conform to certain axioms, but still provide different explanations for the same prediction [5]}.
